This study examined the adsorption characteristics of heavy metal ions (Cr 6+ , As 3+ ) in an aqueous solution using recycled aggregate (RA) and recycled aggregate (RA)/steel slag (SS) composites. The RA and SS are favorable for the absorbent be- cause it contains about 91% and 86.9%, respectively, which are some of the major adsorbent ingredients (CaO, SiO2, Al2O3 and Fe2O3) for heavy metal. Kinetic equilibrium of Cr 6+ and As
